To all whom it may concern Be it known that I, FRANK Krrmrscrrno, a citizen of the United States, residing at etterson, in the county of Jefierson and State of lVisconsin, have invented certain. new and useful Improvements in Valve Mec anism, of which the following is a accompanying drawing, forming a part hereof.

This invention relates to internal combustion engines and the objects of the inare provided with tons 12 and 13 on their respective heads 14: and 15. Preferably the bolts with their heads and the flanges or buttons are-made integral and the flanges are circular, as shown, with the cylinder head care does not have to e exercised to see that the bolts are turned to any specifi 'The fl buttons 12 place.

It quite frethat the exhaust valve becomes weakened by the corrosive and burnin action of the hot gases of com bustion so t at it breaks and the valve, being unsupported, falls by gravity into the cy inder above the piston and on the next upward stroke of the piston is caught bewere to fall would be caught and held buttons 12 and 13.

This inwould no longer be within the guide when vention provides constructions whereby the valve had fallen so that the valve such accidents and damage are obviated. would be free to tip and fall ofl from Refen-mg to the the flanges or buttons 12 and 13. To prevent such an occurrence the cylinder head is undercut to form ledges l8 and 19 and the valves are so placed that they are above said ledges, as clearly shown by the drawings, and said ledges are on a level with the upper surfaces of the flanges or buttons .12 and 13. The heads 14: and 15 of the bolts 10 and 11 are near enough to the valves so that they cannot move sidewise (if broken and lying on flanges 12 and 13 and ledges 18 and 19) suficiently to clear ledges 18 and 19.

The construction illustrated and described forms in effect a cage construction to catch and hold the valves if they should ma apthe cylinder of an overhead-valve internal combustion engine; and Fig. 2 is a bottom plan view of the cylinder head taken on the line a-a, Fi 1, looking in the direction indicated by tie arrows.
